BANFORD GILBERT, OF PITTSBURG, PENNSYLVANIA.

GRIDDLE.

Specification of Letters Patent No. 10,118, dated October 11, 1853.

To all whomz't may concern:

Be it known that I, BANFORD GILBERT, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in the Construction of Griddles; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the annexed drawings, forming part of thisspecification, wherein Figure 1 is a representation of my im- Fig. 2 isa view of the upper plate of my revolving griddle, turned bottom upward.Fig. 3 is a view of the lower plate of my revolving griddle, and Fig. tis a section of my griddle.

In the several drawings the same letters refer to similar parts of thegriddle.

My invention is designed for griddles to be used with cooking stoveswhich I construct in such a manner that when the griddle becomes too hotit may be cooled Without lifting it off the fire, by simply turning theupper plate of the griddle part way around, which admits a current ofair between the upper and lower plates.

In the drawings a, is the lower plate of the griddle, shown also in Fig.3; b, (Fig. 2) is the upper plate. The lower plate of the griddle has acircular rim or flange c, rising perpendicularly from the griddle nearto the edge of the plate. This rim is not continuous being interruptedby four (or more) openings at equal distances apart. The upper plate Z),which is shown in Fig. 2, turned bottom upward to exhibit its shape andconstruction, has two flanges or rims, cl, cl, similar to the flange c,on the lower plate, and like it projecting about half an inch from theunder surface of the upper plate I), at right angles to its face. Theseflanges (Z, (Z, are concentric circles, and are so far apart as toreceive the flange 0, of the lower plate between them. Each of theseflanges (Z, d, has also the openings or intermissions of continuity ofthe otherwise annular flanges of the same size and number, as in theflange of the lower plate, so that when one of the holes in the flangeof the lower plate is opposite to or in a line with the correspondingopenings in the flanges (Z, d, of the upper plate, all the holes in theflange 0, will be in a line with the corresponding holes in the flangesd, 01.

Thus then when the upper plate 6, is placed over the lower plate a, thetwo plates will be separated leaving a space between them equal to thewidth of the flanges, say half an inch. The flange 0, does not fit soclosely between the flanges (Z, cl as to prevent the upper plate beingfreely turned around on the lower plate. The pins 6, e are attached, theformer to the upper, and the latter to the lower plate. These pins aredesigned to facilitate the moving of the plates a, and Z), one upon theother and may be enlarged to form handles for turning or lifting thegriddle at pleasure. They are so placed that when the pins are placed,one exactly over the other, all the corresponding openings in theflanges c, d, and d are opposite to each other and conduct the airfreely be tween the upper and lower plates a, and b. If the upper pin 6,is turned slightly around as in Fig. 1, so that it is no longer exactlyover the lower pin 6', the holes in the flanges are partly shut, theflanges cl, (Z, passing over the openings in the flange 0, andintercepting slightly the current of air between the plates. If the pin6, and with it the upper plate I), were drawn still farther around, theopenings would be closed, and no air would pass in between the upper andlower plates.

If desired the inner flange d, of the upper plate may be dispensed with,without altering the character of my invention.

It is almost unnecessary further to explain the operation of my griddle:it may be used over an open fire, in a range or grate, but ispeculiarly adapted to a cook ing stove. If desired to remove the griddle.from the stove, without uncovering the space in the stove, the upperplate I), may be lifted off from the lower plate a, without uncoveringthe fire.

It is manifest that when using my griddle for cooking, if the holes areclosed, the air inclosed in the space between the upper and lower plateswill get very hot and communicate the heat to the upper plate. Shouldthe upper plate get too hot it may be cooled in turning the upper plateso as to open the spaces between the flanges, which admits a rush ofcool air between the openings into the spaces between the two plates at,and b, and thereby cools the upper plate I), on which the cakes arecooked.

Having thus described my improved gridgriddle, which openings may heclosed at dle, What I claim as my invention and depleasure;substantially as hereinbefore desire to secure by Letters Patent isscribed.
